Title: Improvements in paddle wheel boats
IPC: B63H16/08
Filed: 1952-02-21
Abstract: 700,963. Twin float vessels; propelling and steering. NEWMAN, W.H. G., and NEWMAN, I. R. Feb. 21, 1952, No. 4658/52.

Title: Improvements in devices for gripping, holding and like operations
IPC: A47G21/02
Filed: 1931-02-14
Abstract: 373,190. Grilling and toasting appliances. EVANS, W. J., Highbury Avenue, Bulwell, Nottingham. Feb. 14, 1931, No. 4670. [Class 28 (i).] A domestic device for holding and gripping articles, particularly for holding food during grilling and toasting operations, comprises a handle carrying a number of divergent prongs adapted to be thrust into the article and means on the handle for adjusting their divergence. The device consists of a number of pointed prongs 3 pivoted to a collar 2 which is slidable on a rod or handle 1. The free ends of the prongs pass through apertures, preferably evenly spaced, in a plate or disc 4 secured to the rod 1, movement of the collar 2 on the rod causing the prongs to grip the article. The prongs may be arranged on a circle, as shown, or may be arranged to conform to the shape of article being gripped, and the motion of the collar is limited by stops such as the pins 6. The prongs may be located in radial slots in a grooved flange 7 of the collar and are pivoted by a wire or ring 8, or alternatively the prongs may be made of resilient material and secured non-pivotally to the collar. The prongs may be retained in the retracted or expanded condition by rotating the collar on the rod 1, thus causing the inner ends of the prongs to assume a spiral configuration and bind against the rod. To retain the prongs in any one of a number of adjusted positions, spring catches 11, Fig. 3, similar to those used on umbrellas, may be provided on the rod to coact with a slot 12 in an extension of the collar 2, or alternatively a resilient catch on the collar may coact with a toothed rack on the rod 1. In a modified construction the prongs 3 are carried by a metal tube constituting the handle, through which slides a rod connected at one end to the plate 4 and provided with a laterally projecting pin passing through a longitudinal slot in the tube and attached to an outer collar, slidable on the tube to operate the prongs. The plate 4 may be replaced by a ring surrounding the prongs and slid directly by hand to control the opening and closing of the prongs. The gripping ends of the prongs may be turned inwards slightly and pointed in order to grip the article held and may be formed of channel section.

Title: An improved domestic washing machine
IPC: D06F9/00
Filed: 1937-02-16
Abstract: 485,695. Washing-apparatus. SMITH, A. Feb. 16, 1937, No. 4690. [Class 138 (ii)] A washing-apparatus comprises two pads or brushes or members shaped to resemble hands 14, 34 carried by levers 11, 22 which can be oscillated in two planes. Movement in the vertical plane is effected by the operator by movement of a control lever 8 ; this causes tho pads &c. to approach one another to hold the goods between them. When the lover 8 reaches a predetermined position it operates a switch 29 to switch in a motor 17 to operate an eccentric mechanism 16 to oscillate the pads &c. in a substantially horizontal plane. In a modification one of the pads or brushes may be secured to the bottom of a sink and the upper part &c. alone oscillated.

Title: Improvements in or relating to machinery guards
IPC: F16P1/02
Filed: 1928-02-16
Abstract: 305,824. Dudgeon, H. A. Feb. 16, 1928. Guards.-In order to provide greater protection for the grinding-wheels of tool-sharpening machines of the kind in which the grinding-wheel spindle a is carried by a swivelling-head b in an open-fronted casing c, wheel guards are so carried by the head as to be capable of axial, radial, or angular adjustment or any combination of these adjustments. As applied to the machine described in Specification 295,169, [Class 60, Grinding or abrading &c.], the cast or pressed guard g covering half of each wheel h is adjustably secured by a slotted lug g<1>, Figs. 1 and 2 to a perpendicularly-slotted lug d<2> on the work-rest supporting-arm d, which is angularly adjustable about the spindle bearing e by means of a slotted lug d<1> clamped to the head b. The lugs g<1> may be radial and be bolted to radially-slotted lugs on the arms d, to allow radial and swivelling movements of the guards, angular adjustment being obtained by movement of the arms d and axial adjustment by packing-pieces on the bolts. Fig. 4 shows a modification, in which each guard g is bolted to the slotted flange i<1> of an intermediate member having a curved slot in its flange i, which is bolted to a radial slot in an extension d<3> of the arm d. In another form (not shown), the guards are carried by axially or radially slotted brackets integral with or attached to the head b, an intermediate member being provided if angular adjustment is required.

Abstract: 1,130,466. Potentiometers. WELWYN ELECTRIC Ltd. 1 Feb., 1967 [2 Feb., 1966], No. 4913/67. Heading H1S. A miniature potentiometer adapted for mounting and use on printed circuits and similar electronic circuitry comprises an insulating case 1 of parallelepipedic shape having an axial bore 2 containing an arcuate resistance track 6 and a contact member 31 operable by a spindle 3 rotatably mounted in a flexible toric sealing joint 22 located in the casing, the casing having sealed therein electrical leads 7, (8) (Fig. 1, not shown) for connecting the track to a printed circuit and having provision on the leads for mounting on the printed circuit. The resistance track may be a thin metal layer or may be of metallic oxide, cermet or carbonaceous material with or without an organic binder, formed by silk screening on a support of beryllium oxide, alumina or steatite. The contact member 31 is comprised by two substantially V-shaped blades (Fig. 10, not shown) which interfit, and is located on the lug 11 passing through the insulating support 5 to make contact with the conducting lead 7. The contact member is urged against the resistance track by insulating blocks 25, 23 clamped within the housing. The electrical parts are sealed within the housing by a flexible toric ring 22 which may be of silicone rubber or fluorinated elastomer. Rotation of the contact member is limited by a spur 27 on the disc 26. The conducting leads 7, (8) may be of copper or an annealed copper alloy and may be coated with gold. The end of the assembly distant from the spindle is sealed with a thermosetting resin 18 of, for example, sealing glue or mastic of the epoxide variety, which is covered with glass/epoxide laminate 19. The metal sheath 55 which is secured to the housing by bent-over tabs (61) has a cut-away portion adjacent the conducting leads 7, (8) and is provided with an upstanding earthing tab (65) (Fig. 2, not shown) to aid mounting of the assembly. The sheath aids heat dissipation. The leads 7, (8) may be bent suitably to provide the required mounting on a printed circuit. A modification (Fig. 11, not shown) comprises a rolling contact formed by a swashplate on a ball-and-socket joint.

Abstract: 1,131,297. Injection moulds. COMPO SHOE MACHINERY CORP. 3 Feb., 1967 [21 March, 1966], No. 5448/67. Heading B5A. An injection mould is provided with a valve which is moved to open position against spring or other loading by the pressure of the injected material. In one example a longitudinally slidable tube 36 is biased by a spring 40 to a position in which a hole 38 in the tube is out of alignment with an orifice 34 in a sole plate 14. A first injection through a passage 18 forms an insole 22 including a toe cap 26 and flanges 24, 28. The sole plate 14 is then lowered and a second injection effected through passages 20, 32, 38, 34 to form an outsole 30. An alternative valve comprises a tube terminating where the hole 38 is provided in the tube 36. In another example (Fig. 3, not shown) an injection passage (32a) in the sole plate is connected to the mould cavity by an inclined orifice (34a) and a valve plunger (62) is biased to closed position by a spring (76) acting through a pivoted arm (70).
